I first met the Oracle RDBMS some time in 1988, or possibly 1987, when my manager dumped a small box on my desk and said something like: “There’s this new product called Oracle just coming into the country. Play around with it for a few weeks and then tell us what it’s good for.” The version was something like 5.0.22, and in those days it was a lot easier getting started with Oracle. The entire printed manual set—including Forms 2.0, SQL*Report, and everything else—would fit into a small briefcase and the documentation for the create table statement ran to about three pages. If you check the PDF file for the 11.2 SQL reference manual, you’ll find that create table currently starts at page 16-6 and runs on to page 16-79 for a total of 74 pages. The last time I checked the total page count was for 9i, and that was more than 20,000 pages—and I doubt if the number has dropped in 10g and 11g. With three (fairly slim) manuals for 5.0.22, it didn’t take me very long to learn about everything that Oracle was supposed to do and how to do it efficiently. There weren’t many options, so there weren’t many ways to do things wrong. But how do you get started today when the core of Oracle is hidden under a huge mass of options and features? Worse, the details you really need to understand are covered by a mountain of information that is nice to have, but not critical to getting started. The answer is simple. Step 1: Read the concepts manual so you have an idea of what it’s all about. Step 2: Read Tom Kyte’s book so that you can follow a rational progression of learning and experimenting that leads you from your first “select ‘hello world’ from dual” to the day when you can confidently say things like “we should use a range partitioned IOT with these columns in the overflow for this table because … .” Tom combines three things in this book: a conversational style that makes it easier to read about technical details and understand the “why” behind the “how”; a structured “storyline” so that you see the text building towards a target rather than scattering a disjointed collection of random tips; and an array of carefully constructed demonstrations that teach you how things work and how you should work and think. Consider just one example, indexing. There are many types of indexes, so we need a brief introduction to separate the different types. It’s good to have an idea of how B-tree indexes (for example) actually work so that we can understand their strengths and weaknesses. Then we can move on to the idea of function-based indexes—indexes on “data that don’t really exist.” This gets us to the point of understanding what Oracle can do, but we can (and do) go further with what we can do with Oracle. So we see how we can put the pieces together to create an index that guarantees uniqueness across subsets of the data, we see how we can—on a huge data set—create a tiny, low-maintenance index that identifies exactly the data that we really want to access and minimizes the risk of the optimizer producing a silly execution plan. In principle, it’s all in the manuals, but only if we have the insight to take the naked descriptions of the available commands and see how we can use them to construct solutions to real problems. Tom Kyte supplies that insight, and then encourages you to go further in developing your own insights. Frankly, if every DBA and developer in the world were made to work carefully through Tom Kyte’s book, I’d probably have to start offering consultancy services to SQL Server users because the number of clients needing Oracle consultancy would drop dramatically.

Expert Oracle Database Architecture: Oracle Database Programming 9i, 10g, and 11g Techniques and Solutions, Second Edition Now in its second edition, this best-selling book by Tom Kyte of Ask Tom fame continues to bring you some of the best thinking on how to apply Oracle Database to produce scalable applications that perform well and deliver correct results. Tom has a simple philosophy: you can treat Oracle as a black box and just stick data into it or you can understand how it works and exploit it as a powerful computing environment. If you choose the latter, then you’ll find that there are few information management problems that you cannot solve quickly and elegantly. This fully revised second edition covers the latest developments in Oracle Database 11g. Each feature is taught in a proof-by-example manner, not only discussing what it is, but also how it works, how to implement software using it, and the common pitfalls associated with it. Don’t treat Oracle Database as a black-box. Get this book. Get under the hood. Turbo-charge your career. * Fully-revised to cover Oracle Database 11g * Proof-by-example approach: Let the evidence be your guide * Dives deeply into Oracle Databases’s most powerful features What you’ll learn * Develop an evidence-based approach to problem solving * Manage transactions in highly concurrent environments * Speed access to data through table and index design * Manage files and memory structures for performance and reliability * Scale up through partitioning and parallel processing * Load and unload data to interface with external systems * Think for yourself; don’t take Tom’s word for it! Who this book is for This book is aimed at Oracle Database administrators, at PL/SQL and Java developers writing code to be deployed inside the database, and at developers of external applications who use Oracle Database as a data store. It is the go to book for those wishing to create efficient and scalable applications. Author Information Thomas Kyte Thomas Kyte is the vice president of the Core Technologies Group at Oracle Corporation and has been with the company since version 7.0.9 was released in 1993. Kyte, however, has been working with Oracle since version 5.1.5c. At Oracle, Kyte works with the Oracle database, and more specifically, he helps clients who are using the Oracle database, and works directly with them specifying and building their systems or rebuilding and tuning them. Prior to working at Oracle, Kyte was a systems integrator who built large-scale, heterogeneous databases and applications for military and government clients. Tom Kyte is the same "Ask Tom" whose column appears in Oracle Magazine, where he answers questions about the Oracle database and tools that developers and DBAs struggle with every day.
